Extinction Events in Earth History and Today

Flood basalts and mass extinctions – ancient hyperthermals as analogs for anthropogenic climate change.  Oceanic Anoxic Event (OAE) and mass extinctions are considered to be hyperthermals – usually associated with flood basalt eruptions.[2] Phases of rapid global warming, known collectively as hyperthermals.[1]  Flood basalts are a subset of large igneous provinces (LIPs), the terms flood basalt…

The Current State of Arctic PERMAFROST THAW

Soil layers of permafrost that scientists expected to remain frozen for at least 70 more years have already begun thawing. NOTES In the Canadian Arctic, layers of permafrost that scientists expected to remain frozen for at least 70 years have already begun thawing. The once-frozen surface is now sinking and dotted with melt ponds and…

Climate Scientist speaks on the current Climate Situation

The Mystery of the Antarctic Sea Ice Puzzle, Sea ice Plummeting Suddenly

The amount of ice circling Antarctica is suddenly plunging from a record high to record lows, baffling scientists. A new NASA study by sea ice expert Claire L. Parkinson reveals recent trends in Antarctica’s sea ice extent. CREDITS A 40-y record reveals gradual Antarctic sea ice increases followed by decreases at rates far exceeding the…

New Mechanism for Methane Hydrate Dissociation Discovered

Methane hydrates are ice like structures forming a solid similar to ice. Significant amounts have been located under sediments on the ocean floors of the Earth. Generally, methane hydrates are more stable in fresh water than in salt water. A region allowing the formation for methane hydrates (largely dependent on depth and pressure) is called…

Jet Stream [Polar Vortex] and Climate Change Science

It might seem counterintuitive, but global warming plays a role in blasts of bitter cold weather. The reason: It influences the jet stream. Here’s how. https://insideclimatenews.org/news/02022018/cold-weather-polar-vortex-jet-stream-explained-global-warming-arctic-ice-climate-change Q&A: How is Arctic warming linked to the ‘polar vortex’ and other extreme weather? https://www.carbonbrief.org/qa-how-is-arctic-warming-linked-to-polar-vortext-other-extreme-weather

Get Used to Cold Polar Vortex Outbreaks

It might seem counterintuitive, but the dreaded polar vortex is bringing its icy grip to parts of the U.S. thanks to a sudden blast of warm air in the Arctic. https://www.voanews.com/a/science-says-get-used-to-polar-vortex-outbreaks/4763045.html Q&A: How is Arctic warming linked to the ‘polar vortex’ and other extreme weather? https://www.carbonbrief.org/qa-how-is-arctic-warming-linked-to-polar-vortext-other-extreme-weather

Climate tipping-point potential and paradoxical production of methane in a changing ocean

Authors: Hongyue Dang, Jia Li Dang, H. & Li, J. Sci. China Earth Sci. (2018) 61: 1714. https://doi.org/10.1007/s11430-017-9265-y Access and read the PDF with inline linkages, and reference list here. Abstract The global warming potential of methane (CH4) is about 30 times stronger than that of carbon dioxide (CO2) over a century timescale. Methane emission is hypothesized…
